Not sure whether or not to cite?
use this handy clickable guide
For images that don't need
crediting or permission
take a look at

You can also try multi-search site

Otherwise try these
Creative Commons (CC) sources
(don't forget to give your sources credit!)
or especially for more historical images
Did you know that you can find
